Abstract [en]

Design for environment (DfE) tools, are defined as any type of systematised aid that facilitates the integration of environmental considerations during product development. A variety of DfE tools is available and informed selection based on the company’s, user’s and product’s needs is important for their successful implementation. Through systematic review of the literature, the goal of this paper is to provide a compilation of DfE tools that can be used during vehicle design and development processes. The review resulted in a rich and diverse toolbox of 41 DfE tools the majority of which exhibiting features that are relevant from a vehicle design perspective, such as environmental impacts that are important to monitor for this product category, life cycle considerations, functional and regulation requirements and more. No tool covers all features thus the use of a combination of tools may be necessary. By collecting and presenting the DfE tools available, this paper is expected to assist the adoption and systematic use of existing tools. Gaps and limitations are identified, indicating areas for improvement, for the development of future tools.

Abstract [en]

Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. To address this, a lifecycle approach is needed when vehicle design strategies are developed. The thesis explores the extent that such a lifecycle approach is adopted today and assesses the potential of these strategies to reduce the lifecycle impact of vehicles. Moreover it aims to contribute to method development for lifecycle considerations during product development and material selection.

Current practices were explored in an empirical study with four vehicle manufacturers. The availability of tools for identifying, monitoring and assessing design strategies was explored in a literature review. The results of the empirical study showed that environmental considerations during product development often lack a lifecycle perspective. Regarding the use of tools a limited number of such tools were utilized systematically by the studied companies despite the numerous tools available in literature.

The influence of new design strategies on the lifecycle environmental performance of vehicles was assessed in three case studies; two looking into lightweight design and one at EVs. Both strategies resulted in energy and GHG emissions savings though the impact during manufacturing increases due to the advanced materials used. Assumptions relating to the operating conditions of the vehicle e.g. lifetime distance or for EVs the carbon intensity of the energy mix, influence the level of this tradeoff. Despite its low share in terms of environmental impact EOL is important in the overall performance of vehicles.

The thesis contributed to method development by suggesting a systematic approach for material selection. The approach combines material and environmental analysis tools thus increases the possibilities for lifecycle improvements while minimizing risk for sub-optimizations.
